A New Era in Comfort: '365 Days of Silk'

In an era where comfort is paramount, Train Co., based in Shibuya, Tokyo, is set to unveil their latest creation: the silk innerwear line named '365 Days of Silk' in October 2025. This innovative product is designed to cater to the modern woman, who, according to recent studies, is increasingly aware of her own body temperature regulation challenges. In today’s society, over 60% of women are reportedly experiencing cold sensitivity due to factors such as air conditioning, reduced muscle mass, and dietary habits that lower their body temperature.

Cold sensitivity does not discriminate by season—it can strike in the chilly spring months or during any air-conditioned summer office setting. The key to combating this persistent discomfort is year-round attention. To effectively alleviate built-up cold sensations, the mantra for this new age is “steady and consistent care throughout all four seasons.”

Natural Silk: Luxury for Your Skin

The new collection utilizes high-quality, natural silk that mimics human skin in terms of protein structure, often referred to as “the second skin.” This luxurious fabric helps to maintain warmth during the winter months while preventing overheating in the summer, thereby ensuring utmost comfort throughout the year. Silk's natural properties make it a perfect choice for those looking to ease the consequences of cold sensitivity while enjoying a stylish wardrobe.

The addition of natural cotton in the blend not only enhances the durability of the pieces but also makes them practical for everyday use, as they can withstand daily washing without losing their quality.
